You could try to automatically clean the code, by using
?iconv, say. But the results by not be satisfactory,
depending on what characters were used.

Sweave itself does not compile the LaTeX code. If you
run (in R) 

    Sweave(<filename.Rnw>, encoding = "utf8")

then it will produce the TeX file, which you can then
compile via LuaLaTeX or XeLaTeX [see
e.g. https://www.ctan.org/pkg/lualatex-doc].

For instance, on the command line, just say

    lualatex <filename.tex>

or another programme (such as latexmk) that your TeX
distribution provides.


If this is a vignette, you can specify a Makefile, see
https://cran.r-project.org/doc/manuals/R-exts.html#Writing-package-vignettes
